A fellow I know has a 02 chevy 3/4 ton with a 6.0. After he starts and runs it for for a few minutes, it starts collasping the gas tank. If he leaves the gas cap off, it doesn't have any problems. What is causing this? Thanks,:)

I believe they had a evap canister near the fuel tank on GMT800 vs the underhood one on the GMT400. the GMT800 canister was very easily clogged by dirt road travels.

this is all recycled info, but I have heard it numberous times, so I feel it is somewhat correct.

good luck!

Could even be a bad gas cap...
